We use a dictionary attack to Brainwallet to cover the majority of easy generated wallets.
A Brainwallet refers to the concept of storing Bitcoins in one's own mind by memorization of a passphrase. What we do is taking standard words and mix them to get the key and the address. (because usually people use ordinary and repeatable words to simplify keeping them in mind, for instance: "Home sweet home...")
